Im pretty sure Proof Biz and Bugz were the original members. they wanted to do a 12 man group like the wu. Porter and kuniva were in a group and joined. They had other members (fuzz scoota, couple others) but they left. Eminem got big. left proof alone for awhile. Eminem Released MMLP, iovine gave him shady records, Proof became ems hypeman, Gave D12 the deal. Eminem was heavily featured on the album because it would get them more exposure. he wasnt featured as much on D12 world so the world could get used to D12. Then Proof died, none of the songs without em would do anything, Everyone was already doing solo stuff anyway, Kuniva has been releasing mixtapes, i know swift did too. Bizarre been releasing solo's as with Proof. Porter's producing career took off after Stunt 101 with G Unit. im sure they were all aware Eminem wasnt gonna help them out more than he already has. Eminem was really only proofs friend in the beginning. Why you never hear him say shit about bugz.
